1. Overview

Why Soft Starters?Three-phase AC induction motors are commonly used in a wide variety of indus-trial applications. Due to their starting characteristics, in many cases these motors cannot be connected directly to the power supply system. When starting direct on line (DOL) the motor can see a very high surge current reaching up to 6 times the rated motor current. This excessive current puts stress on the supply system and the switchgear. Also, when starting direct on line, a very high peak torque can occur stressing the driven motor, the mechanical system including auxiliary power transmission parts (V-belt, gears, etc.).

There are several methods for reducing the damaging effects of this excessive starting current. Conventional methods include reactors and autotransform-ers. But these methods only allow the voltage to be reduced in steps whereas a soft starter provides step-free acceleration of the drive system by continuously increasing the voltage over a selected period of time. This approach to starting minimizes the effect of high inrush current on the supply system, the motor and the driven load.

Soft starters provide the following benefi ts:

• Reduced starting current eliminates voltage drops and dips of the supply network

• Smoother acceleration of loads eliminates process or product damage

• Extended lifetime of all mechanical components, e.g. eliminating gearbox damage and resulting in less maintenance and downtime

• Extended motor life

• Reduced maintenance and operating costs

HRVS-DN - Setting a New StandardThe HRVS-DN is an innovative product that provides a fl exible, low cost alterna-tive to fi xed speed (DOL) starting.

Designed for use with standard medium voltage three-phase squirrel cage induc-tion motors, this high-performance digital soft starter ensures smooth acceleration and deceleration.

HRVS-DN is available in all standard internationally recognized medium voltage ratings: 2.3 kV, 3.3 kV, 4.16 kV, 6 kV and 6.6 kV, 10kV, 11kV, 13.8kV and 15kV.

The standard current output range capability is from 60 - 2700A (200 kW to 50 MW).

HRVS-DN is designed and built to meet international standards including:

• IEC • EN

• DIN VDE • NEMA

• UL/CUL • IEEE

The HRVS-DN soft starters are manufactured to the highest quality level. The entire design, production and delivery process has been certifi ed DIN ISO 9001.2000.

The enclosed versions of the HRVS-DN are provided as ready-to-connect cabinet enclosed type units (shown in Figures 1 and 2) or - for OEMs only - chassis type OEM kits are available for building the unit into custom enclosures or other relevant equipment (please note: the complete interface is then the responsibility of the OEM or end user).

1. Overview HRVS-DN - Application ExperienceThe applications for the HRVS-DN medium voltage soft starter are many. From starting motors with limited supply power (including diesel-generators), avoiding inrush current on loaded transformers, preventing over pressure & water hammer in pumping, soft starting and soft stopping general industrial equipment (conveyors, shredders, ball mills, etc)…the list of possible uses is nearly endless.

For more details on Solcon’s application experience around the world see the applications technical notes on our web site at www.solconusa.com.

Examples of applications

• Pumps (fresh water, sewage, hollow shaft, oil, etc.)• Fans and blowers• Extruders• Centrifuges• Mixers• Compressors (screw type, piston, centrifugal, turbo)• Refrigeration compressors• HVAC systems• Crushers• Ball Mills• Conveyors• Marine• Main propulsion• Thrusters• Anchor winches• Bilge pumps


1. Overview How Soft Starters WorkBy using thyristors (SCRs) in a phase angle control mode, reduced voltage control can be achieved. Phase control makes it possible to gradually increase the motor terminal voltage from an initial set point up to the system supply voltage level. The related starting current and the starting torque can be optimally adjusted to the motor/load conditions.

In addition, the Solcon HRVS-DN soft starters provide the “soft stopping” function as a standard feature. Similar to the reduced voltage start, upon a stop command the motor voltage is gradually decreased over time until the motor load stops. Abrupt stopping is avoided, a particular advantage in pumping applications to prevent the damaging effects of water hammer and on conveyor belts where the load may be damaged by an abrupt stop.

Starting and Stopping CharacteristicsInitial voltage

Determines motor’s initial starting torque (the torque is directly pro-portional to the square of the voltage). Adjustable from 10 – 50% of nominal motor voltage VR (with option to extend to 80 % VR).This adjustment also determines the inrush current and mechani-cal shock. A setting which is too high may cause excessive initial mechanical shock and high inrush current (even if current limit is set low, as the initial voltage setting overrides current limit setting). A setting which is too low may result in prolonged start time before the motor shaft will begin to turn. Ideally, the motor shaft should slowly begin to turn immediately after a start signal is initiated.

Current limitDetermines highest allowable current during starting. Adjustable from 100 – 400% of nominal motor current IR (with option to extend to 500 % IR).

Too high a current limit setting will cause excessive current draw from the mains and faster acceleration. A setting which is too low may prevent the motor from completing the acceleration process and reaching full speed. In general this setting should be set to a value that is high enough to prevent the motor from stalling.Note: Current limit is not operational during run mode or during soft stop.

1. Overview Acceleration (ramp-up time)Determines the motor’s voltage ramp-up time, from initial votage setting to full voltage. Adjustable from 1 - 30 seconds (with option to extend to 90 sec).It is recommended that the acceleration ramp time be set to the minimum ac-ceptable value (approx. 5 sec).Notes:- Since current limit overrides acceleration time, when current limit is set low starting time will be longer than the preset acceleration time.- When the motor reaches full speed before nominal voltage is reached, ac-celeration time setting is overridden and voltage ramps up quickly to full voltage.

Deceleration - soft stop (ramp-down time)Used for controlled deceleration of high friction loads.Determines motor’s voltage ramp-down time. Adjustable from 1 - 30 seconds (with option to extend to 90 sec.)Notes:When soft starter is supplied with a by-pass contactor (standard):- soft stop initiation opens the “end of acceleration” contact,- tripping opens the by-pass contactor.Load will then be transferred to the HRVS-DN and voltage begins ramping down.

Pulse start (kick start)Intended to start high friction loads requiring high starting torque for a short period of time. A pulse of 80% VR (without current limit) is initiated to break the load free. Pulse time is adjustable from 0.1 - 1 seconds.After this pulse, the voltage ramps down to the initial voltage setting before ram-ping up again to full voltage based on the starting parameters settings.

Dual adjustmentThe HRVS-DN allows two start/stop characteristics for varying load applications (example: starting and stopping different motors or loads that vary due to chang-ing ambient conditions).Dual adjustment parameters are:Special starting mode: Diesel generator supply*Initial voltage: 10 - 50 % (80 %) VRCurrent limit: 100 - 400 % of motor FLA settingMotor FLA: 50 - 100 % starter Full Load Current (FLC) settingAcceleration time: 1 - 30 sec (with option to extend to 90 sec)Deceleration time: 1 - 30 sec (with option to extend to 90 sec)

*Diesel generator startingWhen starting from older Diesel generator sets (especially those equipped with low cost voltage regulators) both voltage and frequency are unstable causing irregular fi ring of the SCRs. The HRVS-DN is equipped with a special program which overcomes this voltage and frequency instability.

1. Overview Pump control - Start curvesInduction motors produce peak torque of up to 3 times the rated torque during the starting process. In some pump applications, this peak may cause high pressure in the pipes.Standard soft starters drastically reduce the starting torque however peak torque still remains high, causing high acceleration torque and rapid acceleration toward the end of starting process. Peak torque and acceleration torque must be reduced in order to extend the acceleration time. The HRVS-DN provides 6 different starting curves for voltage ramp-up to reduce peak torque and extend acceleration time:Curve 0: Basic curve for commissioning.Curve 1: Standard curve (default). The most stable and suitable curve for the motor; prevents prolonged starting time and motor overheating.Curves 2, 3, 4: During acceleration (before reaching peak torque) the pump control program automatically controls the voltage ramp- up, reducing peak torque.Curve 5: Torque curveBy default, the process should always be started using curve 1. If toward end of acceleration the peak torque is considered to be too high (pressure is too high) starting curves 2, 3 or 4 can be selected instead.

Pump control - Stop curvesWhen stopping a pump motor using a starter that does not have the soft stop feature, motor torque will immediately fall below the load torque. This causes abrupt stalling creating the water hammer phenomenon which can be very damaging to the pump, the pipes, valves, etc. A soft starter with the “Soft stop” feature will smoothly decreases the motor speed to zero, eliminating this phenomenon.

The HRVS-DN incorporates 4 different stopping curves for special voltage ramp-down (decel control) preventing the motor from stall-ing and eliminating water hammer. The pump control stop curves can also be set so the fi nal torque stops the motor when the valve closes.Curve 1: Standard default curve. The voltage is linearly reduced from nominal to zero.Curves 2, 3, 4: According to the actual pump characteristic the soft stop behavior can be selected out of four preset curves.By default, always try using curve 1 fi rst. If the motor stalls quickly instead of slowly decreasing its speed, try stop curve 2. If this still is not satisfactory, try curves 3 or 4.

5. FAQs

Question Answer

Can an HRVS-DN soft starter be used to start a heavy-duty load or a load with a high moment of inertia if themotor will not start direct-on-line (DOL)?

YesBut we need certain data to calculate the minimal starting conditions. Contacttechnical support for assistance.

Can an HRVS-DN soft starter be connected to themedium-voltage bus without using a load breaker?

YesThe HRVS-DN can be provided without a load break switch (with inline and bypass contactors only). A fused load-break disconnect switch at the medium-voltage feeder is sufficient. The fuses are only used as cable protection and protection against catastrophic failure. The motor protection relay is usually included in the circuit breaker or the soft-starter can be equipped with a comprehensive motor protection relay (MPS3000 or equivalent) If an existing circuit-breaker is used, this can remain closed or switches in the no-current condition (exception: under fault conditions)

Can an HRVS-DN soft-starter also be used to startsynchronous motors?

YesA non-excited synchronous motor behaves essentially the same as a squirrel-cageinduction motor. If the motor has reached the rated speed in a non-excited condition(rated slip in induction motor operation), the excitation system (which can besupplied by Solcon) is switched-in and the motor then pulls into synchronized mode.

Is the HRVS-DN soft-starter available in an explosion-proof version?

Yes with certification (EEx-D)[ia]I

Can the HRVS-DN soft-starter be used to start severaldifferent motors or can one HRVS-DN soft starterbe used to start more than one motor?

YesTwo parameter settings can be programmed using the "Dual Adjustment" function. Thismeans that two different motor types can be started. However, there may be littledifference in the actual motor output. Several identical motors can be started. However,due to the higher thermal load, a larger soft-starter (always equipped with a fan), must beused. One (or several) additional cabinets with vacuum contactors can be provided forsequential starting of multiple motors.

When is a tachometer (shaft encoder) required to be usedwith the HRVS-DN soft-starter?

A tachometer is generally not required for standard applications, only for special cases:

Soft stopping with shutdown (power-off) at a specific speedStarting and/or stopping with an adjustable speed profileIf it has to be accurately determined when the motor has reached full speed

Can the HRVS-DN soft-starter be used for braking? YES

Is the HRVS-DN soft-starter also available in an outdoorversions ?

Yes to NEMA 3R (IP67)

Is the HRVS-DN soft-starter designed to meet industrysector-specific and local standards

YESIEC, NEMAUL / CUL in processDNV and ABS or similar upon request

Is it possible to use HRVS-DN soft-starters onsynchronous or slip ring motors?

YesUnless the slip ring motor was originally specified due to especially high startingtorque requirements. Under these circumstances, a soft-starter cannot be used !

Can you use the HRVS-DN soft starter with anymanufacturer’s motor?

YesIn especially critical cases, increased pulsating torques can be observed with some motordesigns. The non-sinusoidal current and voltage waveform of the soft starter does notrepresent a risk.

Can HRVS-DN soft starters operate at high altitudes (i.e.locations 4000m above sea level)?

YesBut the nominal voltage and current have to be reduced based on the derating table(please refer to page 10) and the starting frequency (number of starts per unit time)may need to be reduced.

Can the HRVS-DN soft-starter be operated with supplyvoltages which are not listed in the table (intermediatevalues)?

YesIn this case, the next higher voltage class should be selected, and the actual supplyvoltage specified when ordering.

Can an HRVS-DN soft starter be operated into a step-uptransformer?

YesBut why should a step-up transformer be used when Solcon offers the HRVS-DN inratings up to 15kV?

Does an HRVS-DN soft-starter generate harmonicswhich are fed back into the supply?

YesBut only for a very brief period of time until the bypass contactor closes (low level

Solcon is the only MV soft starter manufacturer in the world to offer this certification.
